Completion of Trial Excavation Programme at Araguaia
LONDON, Feb. 05, 2018 (GLOBE NEWSWIRE) -- Horizonte Minerals Plc, (AIM:HZM) (TSX:HZM) (‘Horizonte’ or ‘the Company’) the nickel development company focussed in Brazil, is pleased to announce the completion of the Trial Excavation programme for its Araguaia nickel project (‘Araguaia’ or ‘the Project’), Brazil’s next ferronickel mine.
Highlights
• A Trial Excavation programme has been successfully completed with all technical objectives met;
• The programme included:
- Pre-mining diamond drilling;
- A test pit with ~27,000 tonnes of ore mined; and,
- Analysis/reconciliation of the mined material.
• Snowden Mining Industry Consultants Pty Ltd (‘Snowden’) supervised the programme on site in Brazil; and,
• The technical and economic results are currently being compiled by Snowden with the information feeding into Araguaia’s ongoing Feasibility Study.
Horizonte CEO, Jeremy Martin, commented:
“The completion of the trial excavation programme at Araguaia, marks another key development milestone for Horizonte. This programme has generated real in-situ data that will allow us to confirm the mining technique, slope stability, grade profiles, dewatering requirement with additional work on ore handling which has allowed the primary crushing design to be finalised.
“The Feasibility Study is well advanced with the focus now around the build-up of the capital costs, the implementation strategy and overall project economics. The recent increase in nickel price will require some additional optimisation work to be undertaken around the mining schedule as we work to optimise the project economics. We look forward to providing further updates to the market as we advance the project permitting and Feasibility Study.”

Further Details
During late Q2 running through Q3, 2017, the Company excavated a test pit at the Pequizeiro deposit (‘PQZ’) at Araguaia. The final trial excavation at Araguaia comprised approximately 27,000 tonnes of material. The exercise was part of the field work completed for the ongoing Feasibility Study and met the recommendations set out by Snowden mining engineers, in the Pre-Feasibility Study, announced in October 2016. The exercise was undertaken by mining contractors under the direct supervision of Snowden, with the support of the Company’s geological team on site.
The objectives of this Trial Excavation programme included:
- Assessment of short scale variability to optimise grade control;
- Assessment of grade control sampling using the channel sampling method;
- Reconciliation of mined blocks with estimated grades and tonnes using two borehole spacings (5m and 10m);
- Reconciliation of contact surfaces as predicted by the resource model;
- Assessment of the presence or not of core stones;
- Samples to measure the granulometry of the ore;
- Confirmation of dilution factors;
- Large scale measurement of bulk density factors;
- In situ confirmation of groundwater and concept of dewatering required;
- Technical support for the mining cost and input assumptions; and,
- Testing the effectiveness of pisolitic ferricrete as sheeting.
The Company collected ‘typical ore’ samples for large scale granulometry and crushing test work, which was completed at the University of São Paulo. Horizonte also conducted detailed mapping and sampling of individual Selective Mining Units (‘SMUs’), measuring 5m x 5m x 2m. All analytical work was undertaken at the ALS laboratories in Brazil and Peru with full QA/QC protocols applied.
Prior to the excavation, a 30 hole (600m) diamond drilling programme was completed on a 5m x 5m grid over the excavation site. The data from this programme has been used for estimation of tonnage and grade for reconciliation with the SMUs excavated during the trial mining.
All of the above objectives listed were met and results are currently being compiled by Snowden for a complete and integrated analysis in the final Araguaia Feasibility Study.
The Araguaia Nickel Project
Araguaia, which is 100% owned by Horizonte, is located on the eastern margin of the State of Pará, north-eastern Brazil, in the Municipal of Conceição do Araguaia (population of 46,206), south of the main Carajás Mining District.
The region has good infrastructure in place including rail, road, water and power. Araguaia plans to produce around 14,500 tonnes of contained nickel in approximately 50,000 tonnes of ferronickel per year from processing 0.9 million tonnes of ore via the proven and widely utilized Rotary Kiln Electric Furnace (RKEF) process route.
